Solar Attic Fan
Cost
The largest problem of using primarily solar energy is the cost involved. Despite advances in technology, solar panels remain almost prohibitively expensive. Even when the cost of the panels is ignored, the system required to store the energy for use can also be quite costly.
Weather Dependent
Although some solar energy can be collected during even the cloudiest of days, efficient solar energy collection is dependent on sunshine. Even a few cloudy days can have a large affect on an energy system, particularly once that fact that solar energy cannot be collected at night is taken into account.
Geographic Limitations
While some areas would benefit from adapting solar power, other parts of the world would receive little benefit from current solar systems. Solar panels still require direct sunlight to collect large amounts of power, and in many areas of the world there are few days that would efficiently power a system.
The price of solar attic fan is higher than that of an electric one (around $200 more), but the dispensation of wiring and the zero operation costs can largely compensate the higher initial price.
Other limitations may be associated with local solar conditions, namely in winter and cold climates, if homeowners want the solar attic fan to fulfill uses besides cooling: in cold climates, with few solar resources, the ventilation provided by a solar attic fan in winter – to fight moisture, for instance - may be insufficient, making electric powered attic fans a more advantageous solution.
